Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...

In a statement, PolyU described the novel Side Hole Polymer Optical Fibre Sensors as "biocompatible, supple and extremely sensitive to very small pressure changes inside the human body". Professor Hwa ...

(Nanowerk News) As buildings age, the demand for effective monitoring of their structural integrity has grown significantly. A breakthrough in nano-optical sensor technology now enables precise, ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...
